The RC Spiral Stairs software can be used for design and analysis of reinforced concrete spiral stairs, also known as “helical rc staircase”.  All internal actions, including the bending moments about both axes, torsion, shear and the axial load are evaluated.  The results are provided in several points along the helical staircase span.  All internal actions are considered in the design of the longitudinal and shear steel. 

RC Spiral Stairs software analysis is based on Finite Element Method, implementing a high order Shell element, and therefore it is the most reliable approach to obtain the internal actions in a helical rc staircase.
